Tauri 2 — desktop · mobile in one codebase

Electron is big and slow. Tauri 2 wraps your frontend in the OS-native WebView, with Rust on the backend, cutting bundles ~10x while shipping desktop and Android from one codebase.

Who it's for

• People who built a small React app and now want desktop / mobile targets
• Anyone looking for an Electron alternative
• Developers who want to touch native features like local SQLite, OCR, STT

What you can do afterwards

• Scaffold a Tauri 2 project (Rust + React + Vite)
• Wire front ↔ back via IPC commands and events
• Persist data with local SQLite using tauri-plugin-sql
• Build signed Android APKs
• Integrate OCR (Tesseract), STT/TTS (Web Speech API)
• Ship to Google Play with AdMob

Flow

Expanding from desktop to mobile

1Purpose and setup

Define why a native web wrapper is justified and establish the build foundation.

2Local boundary

Complete the desktop flow with explicit IPC permissions and SQLite data lifetime.

3Mobile adaptation

Adjust the same capabilities for Android permissions, touch, and background limits.

4Optional features and release

Put OCR, STT, TTS, and ads behind cost and permission gates before store delivery.

Steps 1–4 cover a desktop-only lifecycle, end-to-end. Steps 5–7 are how the same code travels to mobile.

Steps

1. Why Tauri — vs Electron — bundle size · security · performance
2. Project setup — Rust toolchain · create tauri-app · Vite + React
3. IPC — command / event — invoke / emit patterns
4. Local SQLite — tauri-plugin-sql · migrations · offline-first
5. Android build — NDK · keystore · tauri android build
6. OCR / STT / TTS — Tesseract wasm · Web Speech API · permissions
7. AdMob + shipping — ad IDs · Play submission

Prerequisites — frontend-foundations + Rust 1.75+ + Android Studio.
